– Disassembling of the actuator from the valve
Warning
Before starting the disassembly operations it is mandatory to disconnect the
hydraulic power and to exhaust the cylinder and any other pressure retaining
component mounted on the actuator.
Before removing the screws between actuator and valve or adaptor flange or mounting
bracket, the actuator should be connected with appropriate lifting means. Lift the actuator
as shown in Fig.3. The lifting points are appropriate for handling the actuator alone and
not for the valve + actuator assembly.
During the disassembling take care that the mounting coupling block is fix on the valve
stem to avoid any dangerous situation.
